PACA DIGITAL SCIENCE- STEM FAIR 2021 6th grade: Dyes Project Every year, sixth graders study dyes: uses, types, history, and the process of dyeing materials. This year the students began their journey on the discovery of dyes through dyeing a face mask. They then researched about dyes, fabrics and mordants (the substance that allows a dye to “stick”) and wrote short essays about their learning. Students then each conducted an experiment manipulating a variable of their choice related to the dyes process. All materials were chosen from things available at home. They each present the results of their experiments in a short narrated video with a power point to guide the viewer in their process.
6th grade Dyes project variable choices:
Dye substances – foods (fruits, vegetables, teas, etc. )
Materials (cotton, string, eggs, etc. )
Mordants – natural available at home
Dye process changes (order, time, washing, wet/ dry, etc. )
